SXmini M Class (TEMP CONTROL)

[Impulso]

Until scope results are available, it would be purely speculative at this point..

It would be quite helpful if another thread was created in this forum to discuss the technical aspects of YiHi's board, post civil comparisons between other available technologies, etc..

There was another thread discussing the technologies, which was unfortunately closed after consultation with staff, due to repeated disruptions. Perhaps a fresh start in another will fare better, and provide useful, constructive, information for those interested in discussion of that nature..

Agreed! Although once someone scopes this and explains it, it may be moot?

^^ that's true and scope results from Busardo are being worked on now, I believe.

Hope so..... a scope in power mode and a scope in TC mode should be very beneficial..... come on Pbusardo....you ain't got time to sleep....LOL

Dang that's too bad. I just ran a few scope captures in temperature limiting mode and was gonna post them. I'm not an engineer but I can halfway read a scope.

Why not be the one to start another thread? It could be titled something like "YiHi SX350J Owner's Technology Thread" or something similar... I'm sure many would like to see your results..

EDIT: Just a suggestion of course... Your results would be welcome here regardless..

Did a bit of searching as this "hum" interested me..... found this video put up yesterday.... could the mini be using PWM in TC mode?

This video may help with understanding the "hum" absent any updated info from Yihi...

I did watch the whole video and this guy really seems to give an honest review of his new SX Mini M class device. I think I will watch it again, but one thing he pointed out was the pulsing on TC mode changing when changing the joules setting. He demonstrated that at the higher joules settings such as at 50J the intensity of the voltage was greater therefore causing more spacing of the actual pulses where the device achieves your set temperature. At lower settings the pulsing was more frequent and less noticeable giving it a more smooth vape with a more constant voltage. I always thought that the joules setting was just used to get the unit to your temperature quicker, but it appears that may be true, there are other factors in play even after you reach your temperature depending on your joules setting. He also pointed out that the amps draw may be quite high if you are using a high joules setting even pushing the limits of most batteries. That may have something to do with the reason why we only have 50J and not 60J as we have in power mode with 60W.

I tested this out myself briefly and do feel the pulsing using 40j and even more at 50J. Maybe for that reason I have found myself using more at 22J or 28J at the highest settings for my vape liking.

Now I am even wanting to know even more when folks like Pete Busardo throw the device on a scope and pull out the graphs. We are looking for that great sweet spot where every pull is just like heaven. Even after having this device for 12 days now I am still learning how best to use it.

Well a couple reasons. 1. IMO to many threads already 2. Don't know how. lol And what I captured may or may not be overly accurate or useful to get an overall assessment as I cant take very long captures with my crappy usb pc scope before it completely clogs up my pc. I'll post links here for those interested anyway. Pbusardo will tell us more soon I'm sure.

Full Signal Shows where the temperature limit kicks in. It's pretty obvious.

5Hz is only showing the frequency between one of the lowest time periods after temperature limiting kicked in.

17Hz is showing one of the higher time periods after temperature limit kicked in.

49Hz is showing a fairly regular signal without temperature limits kicking in.

Tres interesante: apparently low-level noise and filtering?

What is the name of the USB device you are using? And, is it possible that what I see as noise is coming from your computer? More specifically, the USB port?

Thank you in any case!!

Yea there's a bit of noise but that shouldn't impact the frequency of type of signal that much. Mainly the amplitude and I wasn't really measuring or looking for that. Like I said it may not be overly accurate so take it with a grain of salt.

I'm sitting here debating the attempt at a dual coil in my Infinite Magma clone now.

Might be a dumb question, but what do you use to block off the other air hole anyway? If i did decide to give the single coil a try that is.

The AFC ring has holes for single coil builds.

For those using a Samsung INR 25r in the SX Mini, how manyML of juice are you able to put through it before you need to change?

Not sure on how many mL it went through. I put a fresh battery(Sammy 25R) in Tuesday night and I just got the low battery alert. 21124.2 joules total

 

[dam718]

It's a different type of battery, I know... But I am also getting between 21-22K Joules of vaping with the LG HE4

 

[dam718]

So mine definitely has the buzzing sound in TC as well.

I did some quick setting changes to see if I could alter the sound of the buzz.

What I found was, it didn't seem to matter what temperature I set it too. The buzz stayed the same.

If I changed the Joules setting it would be very quiet at low joules, and get progressively louder as I moved the joules up. Kinda strange.

Also, it's worth noting that the frequency of the buzz never seemed to change, only the volume.

I got an e-mail from Phil yesterday, and he said he was scoping it out tonight. I'm gonna send him another e-mail about the buzzing, in case he didn't notice it.

Not so sure holding it up to his ear is something he normally does during his tests... LoL

Magma (Infinite clone) However, the Magma can handle that too. The nice thing about the Magma is that for single coil, you can close off the other air hole. Most other RDAs don't offer that.

Not really true I think...I have more than adozen different RDAs and many have this option one way or the other! Anyway, the magma is great!

The Magma has a ring with 3 sets of four holes of different sizes. Two of those sets are are opposite of each other, while the other is orthogonal to the other two. So if you want dual coil, you use the two sets that are opposite of each other. If you want single coil, you use the middle set that is orthogonal to the other two. In that single coil configuration, the ring blocks off the other air hole.

I agree... maybe someone will put up such a thread....

As stated in my previous post.... could the mini be using PWM in TC mode? (heavy on the ?)

Had a conversation with a buddy..... probably not PWM.....I received information but better it be a subject for a different thread......

 

[TheotherSteveS]

Isnt it supposed to be a pukka buck-boost?? Where did this PWM idea come from?? Sorry I missed the last few pages...lol!

Folks hearing a hum/rattle..... video posted earlier also talks about noise.... I mentioned that the only devices I recall making rattle sound were pwm....but info I received doubts it's pwm....

hope this answers your question...

Ok thanx! I should have read a few pages back. To be honest I doubt its pwm also....where is busardo when you need him!!

SXmini M = PWM "Probably Worth More" than the $200 bones I laid down for it.
